When a yellow exclamation mark appears on the car dashboard, there are four possible scenarios: general malfunction, automatic transmission failure, abnormal tire pressure, and lighting system failure. Below is a detailed analysis of these four situations: General Malfunction: A triangle with an exclamation mark inside indicates a malfunction in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission failure warning light, indicating a transmission malfunction or transmission fluid level below the normal range. Transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark inside a horizontal line under a bracket represents the tire pressure monitoring warning light. This light turns on when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Failure: A yellow bulb with an exclamation mark is the lighting failure indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue. Additionally, a red exclamation mark inside a circle with a bracket represents a brake system warning, indicating either brake system failure or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents.

Is It Necessary to Use Fuel Cleaner for a New Car?

It is not necessary to use fuel cleaner for a new car. Fuel additives are mainly used to clean carbon deposits in the fuel injectors and intake valves, protect the engine, reduce wear, lower emissions, decrease fuel consumption, and restore power. They can be added when the mileage reaches around 50,000 to 60,000 kilometers. The relevant introduction to fuel additives is as follows: Functions of Fuel Additives: Fuel additives, commonly known as the third generation of gasoline detergents (also referred to as gasoline detergents or fuel additives), are designed to address carbon deposit issues in the fuel system of electronically fuel-injected vehicles, quickly restore the engine to optimal performance, and compensate for certain deficiencies in gasoline properties while imparting new beneficial characteristics (such as improving atomization, reducing wear, protecting the engine, and lowering emissions). Composition of Fuel Additives: Fuel additives are primarily composed of more than ten ingredients, including nano-molecules, cleaning activation factors, antioxidants, anti-corrosion agents, and demulsifiers. They are specifically developed to target harmful components in fuel, such as sulfur, gum substances, and engine carbon deposits, thereby enhancing power, promoting combustion, providing anti-oxidation, anti-wear, cleaning, dispersing, demulsifying, anti-corrosion, and lubricating effects.

Why does the vehicle idle speed suddenly increase?

Vehicle idle speed increases due to faults in the engine intake system and fuel system. Here are the relevant explanations: 1. In the engine intake system, components such as the throttle body assembly, air flow sensor, engine intake pipe, engine vacuum tube, and engine exhaust gas recirculation valve may be damaged. 2. Throttle body assembly: The throttle controls the air entering the engine, acting as a controllable valve. After the gas enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. Simply put, it functions similarly to a human throat. If this component fails and the throttle opening becomes uncontrolled, the throttle opening increases, causing the vehicle's idle speed to suddenly rise. 3. Air flow sensor: It converts the inhaled air flow into an electrical signal and sends it to the electronic control unit (ECU) as one of the basic signals for determining fuel injection. It is a sensor that measures the air flow entering the engine. If this component fails, the vehicle's ECU will inaccurately determine the amount of air entering the engine. Since the ECU cannot accurately judge the air intake, the vehicle may exhibit a sudden increase in idle speed. Engine vacuum tube: This component maintains the engine's vacuum level to ensure smooth operation. If the vacuum tube is damaged, the internal vacuum level of the engine becomes unstable. To maintain normal engine operation, the ECU will increase the engine speed, resulting in a sudden rise in the vehicle's idle speed.

What does China 6b mean for vehicles?

China 6b refers to the second phase of the China 6 emission standards. According to the plan, the "China 6" standard will be implemented in two phases: China 6a and China 6b. The first phase started on July 1, 2020, prohibiting the sale, registration, and licensing of vehicles that do not meet the China 6a emission standard. The second phase, starting from July 1, 2023, prohibits the sale, registration, and licensing of vehicles that do not meet the China 6b emission standard. More details are as follows: 1. The "China 6" standard is an upgrade from the China 5 standard. Compared to the "China 5" standard, "China 6" will strictly control the emission limits of pollutants. The standard requires a 50% reduction in carbon monoxide emissions for gasoline vehicles, a 50% reduction in total hydrocarbons and non-methane hydrocarbon emission limits, and a 42% stricter nitrogen oxide emission limit. 2. Except for carbon monoxide and particulate number (PN), which remain unchanged, the emission standards for other gases under "China 6b" are almost twice as strict as those under "China 6a", and even more stringent compared to "China 5". The most notable change is the nitrogen oxide emission standard for diesel vehicles: the "China 5" standard was 180mg/km, while "China 6b" is 35mg/km.

What causes excessively high NOx emission data in Dongfeng Tianlong?

Dongfeng Tianlong's excessively high NOx emission data requires checking the fault codes, likely due to a damaged oxygen sensor. The following factors can contribute to NOx exceeding standards: 1. Fuel system blockage: Possible causes include clogged fuel lines, blocked fuel injectors, or insufficient fuel injection, leading to excessive oxygen content in the engine. This results in immediately emitted CH and CO levels being too low to reduce NOx, consequently causing excessive vehicle emissions. 2. Malfunctioning three-way catalytic converter: Another potential cause is failure of the three-way catalytic converter. When the catalytic converter fails, it cannot catalyze the chemical reactions between CH, CO and NOx, naturally resulting in excessive vehicle emissions.

How much spray paint is needed to paint a motorcycle?

A full-body paint job for a motorcycle generally requires 1.8 to 2.2 liters of spray paint. Below is an introduction to the automotive painting process and paint composition: Automotive Painting Process: Automotive painting typically uses baked enamel. In automobile manufacturing plants, after the frame and body are welded, the next step is painting. Types include standard paint, metallic paint, and pearl paint. The automotive painting process involves applying putty, sanding, and spraying paint. Automotive Paint Composition: Automotive paint generally consists of four basic components: film-forming substances (resins), pigments (including extender pigments), solvents, and additives. Automotive paint types include standard paint, metallic paint, pearl paint, clear coat, and matte paint.
